Also I'm not sure if I buy the whole thing about Anakin having been born on Tatooine, hence the outfit on his ghost. Even the PT had the Jedi's wear different uniforms, and even express different ideologies through clothing, so I don't see why the pre-PT lore couldn't have gone for a similar thing.
The lack of discipline with respect to uniforms among the Jedi is one of the many things I disliked about what Lucas did to them in the PT. The fact that the Jedi are explicitly called "knights" should have informed their cinematic depiction a bit more. Knights are organized, disciplined, and militaristic - and even if the analogy to monks is made, monastic orders (be they Catholic, Orthodox, or Buddhist) are known for wearing a single, distinctive garb, to represent a giving up of individuality (in direct contrast to what Lucas came up with in the PT).
The "wear what you want" thing is reflective of the general problem with the Jedi in the PT, summed up nicely by Mike Stoklasa as "disorganized hippies running a war."
Anakin's force ghost robes obviously needed to convey visually (and in very little time) - that he was no longer evil. thus he could not be wearing the color he wore as Vader. Making him look just like Obi-Wan was the most effective and expedient visual shorthand they could come up with. The most reasonable in-universe explanation still strikes me as being that it is a Tatooinian garb - Obi-Wan spent most of his later life there, and Anakin (whether or not he was born there) certainly lived there at the time he met Obi-Wan and went off with him on his damn fool idealistic crusade.
And as to Luke's TFA uniform - it's not a carbon copy of the PT moisture farmer robes, so I'm happy about that. The fact that he's a Jedi Master now makes me okay with him having moved beyond the uniform of a Jedi Knight. also the fact that he's the last of the Old Order / First of the New means he's earned the right to wear something unique - with the color white being perhaps a repudiation of the Jedi Order of Old.
